DZ01 Permeability Test System

DZ01 Permeability Test System is designed and manufactured based on infrared sensor and coulometric sensor conforms to the requirements of ASTM D3985, ASTM F2476, ASTM F1249 and ISO 15106-2. This instrument can be used to measure the oxygen, carbon dioxide, and water vapor transmission rate of barrier materials with high, and medium barrier properties with a wide testing range and high testing efficiency. The instrument is featured with patented design of integrated block consisting of 3 test cells. Equipped with high precision sensors and professional computer-controlled system, the instrument can regulate and control the temperature, humidity and flow rate precisely, which guarantee the testing sensitivity and repeatability of test results. DZ01 is applicable to determination of oxygen, carbon dioxide, and water vapor permeability of plastic films, sheeting, paper, packages and other relative packaging materials in food, pharmaceutical, medical apparatus, consumer goods, photovoltaic and electronic industries, etc.

Test Principle

The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. The upper chamber contains oxygen/carbon dioxide/water vapor and the lower chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, the molecules of oxygen/carbon dioxide/water vapor permeate through the specimen into the nitrogen side and are taken to the coulometric sensor/infrared sensors where proportional electrical signals are generated. The transmission rate of oxygen/carbon dioxide/water vapor is then obtained by analyzing the signals and calculating the volume of individual gas is measured by the correspondent sensor. For whole package samples, high purity nitrogen flows inside the package, while the outside of specimen is maintained in a high concentration of oxygen/carbon dioxide/water vapor.

Product Features

Patented Infrared Sensor Technology The instrument uses Labthink’s proprietary infrared sensor for water vapor analysis, which has excellent precision, repeatability and service life. Higher sensitivity and stability make it unnecessary to calibrate with distinct reference films for different test ranges and the interval between calibrations is extended. The test range of the sensor can be set automatically according to the transmission rate of the specimens without manual adjustment. The coulometric sensor can be re-coated with electrolyte agent when needed.

New Generation Integrated Testing Block The patented three-cell integrated test block structure using advanced thermodynamics and hydrodynamics analysis greatly improves the temperature, humidity and flow measurement accuracy across the three test cells and supports sequential testing of three samples.

Automatic Control of Temperature, Humidity and Flow Rate The internal temperature and humidity of the instrument are automatically adjusted with temperature and humidity sensors, maintaining the stability of the test specimen environment. Automatic flow rate control ensures constant flow during the testing process and minimizes any errors caused by an unstable flow rate.

Easy-to-use and High-efficiency System The automatic test mode, combined with the instrument features, eliminates the need for manual adjustments to quickly obtain accurate results, saving training costs and releasing staff from manual monitoring so that they are available for other tasks. The professional test mode provides flexible and rich instrument control functions to meet individual scientific research needs. Unique, optional DataShieldTM system, meets the requirements for centralized management of user data. It supports a variety of formats of exported data. Reliable security algorithms are used to prevent data leakage. It supports universal wired and wireless LAN, optional private wireless network, and supports third-party software.

User-oriented Service Concept Adhering to our user-oriented service concept, Labthink has created a customization system that provides flexible and comprehensive customization services for the accommodation of non-standard specimens and packages.
